Fix.TWO_PHASE_NUMBERING
The signature TWO_PHASE_NUMBERING
combines the signatures ONGOING_NUMBERING
and NUMBERING
. It describes a numbering process that is organized in two phases. During the first phase, the numbering is ongoing: one can encode keys, but not decode. Applying the functor Done()
ends the first phase. A fixed numbering then becomes available, which gives access to the total number n
of encoded keys and to both encode
and decode
functions.
